Traditionally, Sugi wood (cryptomeria japonica L.f., also called Japanese cedar) was used. The process involves charring the wood, cooling it, cleaning it, and finishing it with a natural oil.
The oil used for final finish is tung oil.

Hello, great article! Do you know where I can buy that door latch? I’d love it for my shed. I tried googling “drop bar latch” and lots of combinations of it, but couldn’t find anyone who seeks that design. Thanks!
